Quote:I just collimated the scope after trying to fix some astigmatism in the C14. Well I did not improve the astigmatism and now the collimation screws are too hard to turn. Anyone have any advice on the collimation screws, and any advice on the astigmatism?

Quote:There are 3 small washers that must be installed with them,I have wondered why they aren't locking type or the Bobs knobs dont have the semi locking compound on them to keep from moving over time.I just shudder every time I see a dust cover put on with those things JUST under it, A slight bump or laying someting on an ota.. you can keep em.. A properly collimated stock set has done me well for 3 decades..I have had them, but I havent had the best luck with them, they had to be messed with every time or every other time I used the scope.If they could fix the creep and lower the profile another 1mm I would try them again. it is a good idea.I have thought of a small wireless collimating system would be cool ecpecially for Large SCT's, or wired on Newtonians.oops there goes my first million....
